Karl Heinz Marbaise commented on MCOMPILER-357:
-----------------------------------------------
There are several issues with your setup:
I would suggest to get it like this:
{code:xml}

Keep your avro files in the location you have...
Furthermore If you use the above configuration everything will be generated
correctly and the classes will be compiled correctly:
{code}

target/

└── inputFiles.lst
14 directories, 14 files
{code}
I can import this project without any errors into Eclipse If I add the
{{target/generated-sources/avro}} to the build path which is a lack of support
of the avro-maven-plugin which should handle this correctly or more accurate
using a m2e connector in Eclipse...
> Compiler ignores generated-sources not used in regular sources
> --------------------------------------------------------------
>
> Key: MCOMPILER-357
> URL: https://issues.apache.org/jira/browse/MCOMPILER-357
> Project: Maven Compiler Plugin
> Issue Type: Bug
> Affects Versions: 3.8.0
> Reporter: Leonardo Contreras
> Priority: Major
> Labels: build, maven
> Attachments: GenerateAndCompile.zip
>
>
> When using the a generated-sources directory, if no classes use the ones
> defined in the generated sources it works ok, but if one of the non-generated
> classes uses a generated-sources class, the ones not used are ignored.
> I worked around with an unused import.
> Attached is a project that shows the issue.
